for two years my wireless router (linksys wrt54g) worked flawlessly with my ibook. we recently bought an imac, so both computers shared the same wireless network. after about a month the ibook began cutting out on me. it would work for about an hour then it would stop picking up a connection completely. i took the suggestion of a livejournal member and disconnected the power cord of my entire network for the evening. woke up, it made no difference. so i began to suspect an airport card issue. took it to the apple store, they ran "internet radio" on it for 24 hours straight without losing a connection. so it wasn't that. so, today i bought a new wireless router but the issue remains. is it possible that the issue is with the wired router itself? i am just confused because my imac has yet to lose a connection throughout this process. i only seem to be having a problem with my ibook. any suggestions/links to patches/etc. would be greatly appreciated.
